Water filter installation for contractors

Why a plumber would subcontract this at all

Most of the plumbers we work with are entirely capable of fitting the equipment. What they would rather not own is the part either side of the fitting: deciding what the water calls for, and the maintenance tail that follows for the next decade.

Sizing is where water treatment stops being plumbing. Getting it wrong is rarely visible on the day and frequently visible a year later, when a softener sized off a guessed hardness figure is regenerating twice as often as it should, or a carbon filter specified for free chlorine turns out to be on a chloraminated supply and exhausts early. Neither failure looks like a plumbing fault, and both come back to whoever signed the job.

The maintenance tail is the other half. Water treatment generates a service relationship whether you want one or not, because every system in this category consumes something on a schedule. If that is not a business you want, handing it over at the start is cleaner than inheriting it.

How the arrangement works

You keep the customer. We are not interested in a relationship with your client beyond the water treatment scope, and we will not quote them for anything outside it. If they ask us about a boiler or a bathroom, the answer is that it is your job.

We test, size and specify, then either install or hand you a specification to install yourself, whichever suits the job. Plenty of contractors want the sizing and the certification reasoning and would rather do the pipework with their own crew, and that is a perfectly good arrangement.

Where the work needs a licensed plumber under the rules of that jurisdiction, it is done by one. Pennsylvania licenses plumbing at municipal rather than state level, so the requirement genuinely changes between townships, and we check rather than assume.

The jobs that come to us most often

• A well property where the buyer's inspection turned up bacteria or nitrate and the closing is in three weeks.
• A softener that was fitted years ago by someone no longer trading, with no paperwork, that the homeowner now wants serviced rather than replaced.
• A commercial kitchen or coffee operation where the equipment manufacturer specifies a water quality the incoming supply does not meet, and the warranty depends on it.
• A lead service line replacement where the homeowner wants point-of-use filtration in place for the period before and shortly after the work, which is when lead readings spike.
• A whole-house filter that needs a bypass retrofitted because the original installation did not include one, and every future service call means shutting the building down.

What we will tell your customer

The same thing we tell everyone, including when the answer is that they do not need the equipment. If we test a property and the water does not justify treatment, we will say so, and that is worth knowing before you refer someone expecting a sale.

We work from certified reduction claims rather than general ones. If a product is not certified to the NSF/ANSI standard covering a contaminant, we do not claim it reduces it. That keeps you out of the position of having passed on a claim that does not hold.

Sizing, and the two numbers that decide it

Flow rate and hardness settle most residential specifications between them. Flow rate determines whether a unit can supply the building at peak demand without a pressure drop somebody notices in the shower, and it is set by fixture count rather than by occupancy. A large house with two people in it still needs the flow a large house demands.

Hardness sets softener capacity, and capacity is what determines regeneration frequency. A unit sized against a guessed figure regenerates too often, consumes salt at a rate the customer notices on the bill, and wears through resin faster than it should. Neither symptom appears on the day of the install, which is why this is the number worth getting from the utility rather than estimating.

Coverage and getting in touch

We cover New Jersey, Pennsylvania, Connecticut and New York, with researched local water data for the towns on our service area pages. For trade work that data is the useful part: we can usually tell you the source water, the disinfectant and the hardness for an address before anyone visits it, which is often enough to scope a job over the phone.

Use the form with a note that you are a contractor and describe the job. If it is straightforward we will give you a specification without needing to attend. See also commercial installation and our installation process.
